BURNER.

Application filed March 13, 1922.

To all whom it may concern:

Be it known that l, Lomm D. MASON, a citizen of the United States, residing at Kokomo, in the county oi Howard and State of Indiana, have invented new and useful Improvements in Burners, of which the following is a specification.

This invention relates to an improved burner construction for kerosene stoves, and an object of the invention is to provide a combined burner and air mixer for kerosene cook stoves or the like, which will cause a smooth, even burning, and eliminate smoke and dist'aseftul odors such as are frequently contingent with the use of kerosene stoves, and one in which the wick will work smoothly.

Other objects of the invention will appear in the following detailed description taken in connection with the accompanying draw ing wherein:

Fig. 1 is a complete side elevation of the improved burner.

Fig. 2 is a fragmentary side elevation of the burner.

Fig. 3 is a top plan of the improved burner having parts removed.

Fig. 4: is a vertical section on the line l4 of Fig. 3.

5 is a detail section taken on the line 55 of Fig. 3.

Referring more particularly to the drawings, the improved burner structure comprises an outer and inner wick tube 1 and 2 which are spaced sufliciently to permit the passage of an approved type of wick therebetween for feeding the kerosene or analogous fuel to the upper edge of the wick for burning. The inner tube 2 has the usual hook 3 attached thereto and the wick. lifting device comprising the shaft t and ratchets 5 is provided for raising and lowering a wick between the outer and inner tubes 1 and 2. The shatt 4 is enclosed in a suitable housing 6 and has a handwheel 7 thereon by means of which a wick may be adjusted in the usual approved manner. An air mixer structure is associated with the wick tubes 1 and 2 and comprises a perforated supporting plate 10 which is supported within the inner tube 2 by suitable supporting rings 11. A collar 12, rests upon the perforated supporting plate 10 and it is provided with annular corrugations 13 in one of which a second perforated disc or Serial No. 543,341.

plate 14L engages. The perforated disc 14: is spaced outwardly or upwardly from the perforated supporting disc 10 as clearly shown in 4 of the drawings, and it has a cowl supporting sleeve 15 resting thereon and attached thereon by means of the bolt 16. The belt 16 extends vertically through the axis of the sleeve 15 and through the apex of the cone shaped cowl or top 17 which is positioned above the upper end of the collar 12 and extends outwardly beyond the perimeter of the collar for acting as a deflector to deflect over the upper end of the sides between the inner and outer wick tubes 1 and 2 for directing air to be mixed with the flame issuing from a wick carried by the burner structure. An air guiding collar 18 is mounted about the outer surfaces of the outer tube 1 resting upon horizontally extending supporting arms 19 which are soldered or otherwise suitably attached to the outer tube l. The collar 18 is'provided with notches which engage over the supporting arms 19, as clearly shown at 20 in Figs. 1 and 4: of the drawings. The collar 18 gradually decreases in diameter or tapers inwardlyso as to extend upwardly to the line coinciding with the base of the cowl 17 from which point it flares outwardly providing an outwardly flaring flame guide 21 for guiding the flame after the air has been mixed therewith over a relatively wide area.

It is, of course, to be understood that the invention may be constructed in other manners and the parts associated in other relations and, therefore, I do not desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus described my invention what I claim is:

1. ln a burner, the combination with inner and outer spaced wick tubes, 01'' a per: forated supporting disc positioned within said inner tube, a collar supported thereby, a second perforated disc carried by said col lar, and a cowl supported from said. second disc above the upper ends of said wick guiding tubes.

2. ln a-burner, the combination with inner and .outer spaced wick tubes, a pertorated supporting disc position within the inner tube, a collar supported thereby, a second perforated disc carried by said collar. a cowl supporting sleeve carried by said disc, and a cowl supported by said sleeve above the upper ends of said wick guiding tubes.

3. In a burner, the combination with inner and outer spaced wick tubes, a perforated supporting disc position within the inner tube, a collar supported thereby, a second perforated disc carried by said collar, a cowl supporting sleeve carried by said disc, a cowl supported by said sleeve above the upper ends of said wick guiding tubes, an air collar positioned about the outer Wick guiding tube, and having an outwardly flaringupper end.

4. In a burner, the combination with inner and enter spaced wick tubes, a perforated supporting disc position within the inner tube, a collar supported thereby, a second perforated disc carried by said collar, a cowl supporting sleeve carried by said disc, a cowl supported by said sleeve above the upper ends of said wick guiding tubes, an air collar positioned about said outer wick guiding tube and having its sides inclined inwardly to a point on the same plane with the base of Said cowl, said air collar flaring outwardly from the base of said cowl.

In testimony whereof I a llix my signature.
